In the case of non-aligned parallel cracks, on-site service needs to decide whether they should be treated as coalesced or separate multiple cracks for Fitness-for-Service. Criteria and standards for the adjustment of multiple nonaligned cracks are very different from one another in existing resources. Furthermore, those criteria and standards are often derived from on-site service experience without rigorous and systematic verification. Based on this observation, the interaction between an edge and an embedded parallel crack is investigated to correlate criteria and standards from various resources in order to recommend the usage of those standards for the purpose of Fitness-for-Service. In this study, depending on the crack ratio a1/a2, what may be deemed conservative by one standard, leading to aligned cracks for a given separation distance, H/a2 and S/a2, may be deemed non-conservative, or non-aligned, by another standard. Examples are given to show this phenomenon.","PeriodicalId":100659,"journal":{"name":"IMPACT of Computing in Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86518217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has 90 cities consisting of small, medium, big and metropolitan cities. It is deemed necessary to establish a system to render cities more modern and advanced in the hope of improving the prosperity of all Indonesian people. The adoption of smart city system should be implemented by making the best use of technology. The smart city concept for developing countries consists of eight parameters, namely smart energy, smart infrastructure, smart people, smart health, smart mobility, smart governance, smart education and smart technology. These parameters were identified from the analysis of the data collected from cities in Indonesia, which are distinguished into four different types of cities, namely small city, medium city, big city and metropolitan city. These principal parameters of smart city in Indonesia have a relationship that remains strong and positive as it correlates with urban population growth, and this correlation is made using differential modelling.","PeriodicalId":100659,"journal":{"name":"IMPACT of Computing in Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84011571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is solved by using MATLAB and the consistency test is carried out. Finally, the weights are calculated and ranked according to AHP. The optimal solution was evaluated by Analytic Hierarchy Process (AHP).Then the case study of Kariba Dam is carried out. The results of the first and the third schemes are very close. Therefore, in order to further analyze the accuracy of the AHP results, we will focus on the comparison of schemes 1 and 3 with a detailed analysis of the third scheme. A multi-objective planning model with a minimum number of dams and a minimum construction cost is established. The model takes into account such factors as the amount of power generated, water capacity, and the number of dams. Finally, LINGO is used to solve the model. In data collection, some dams do not have accurate information, and regression equations are established by using known information to predict other information through EXCEL fitting, finally obtaining the optimal solution. Finally, the accuracy, applicability and flexibility of AHP results are verified.","PeriodicalId":100659,"journal":{"name":"IMPACT of Computing in Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81063887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some scholars have made an electro-osmotic method to treat silt and combine pile-loading to reduce the energy consumption of electric energy. In this paper, the effects of electro-osmotic treatment combined with pile-loading experiment on the consolidation of municipal sludge and the content of heavy metals in the sludge before and after electro-osmosis are analyzed and the conclusions are drawn.(1)The combination of electro-osmotic method and pile-loading experiment has strong capacity of drainage consolidation.(2)The contents of copper and zinc decreased obviously, and the electro-osmotic method combined with pile-loading method had a certain effect on the treatment of heavy metals in silt.

They studied the characteristics of electro-osmotic reinforcement of contaminated soil from domestic sources, and analyzed the four parameters of water content reduction percentage, energy consumption per unit displacement, shear strength and soil settlement. The sequence of primary and secondary factors influencing the effect of electro-osmotic drainage reinforcement of contaminated soil is obtained: Power supply voltage > electrification time > initial water content > CaCl2 addition > electrode material[1]. In the study of treatment of heavy metals in sludge of municipal sewage treatment plant by electrodialysis, Chen Wenting[2] used electrodialysis device to carry out electrodialysis experiment on sludge of sewage treatment plant. Samples were taken every 2 hours and then treated with Tessier five-step method. It is found that electro-osmotic method is feasible for heavy metal treatment. Wang Jun and others made use of the independently developed experimental device in 2014 to conduct indoor model tests on the combination of electro-osmotic method and closed vacuum preloading method to strengthen soft clay foundation. It was found that vacuum preloading and electro-osmotic method can promote each other under the combined action. The results show that the compatibility is better than that of vacuum preloading alone in the treatment of soft clay foundation[3]. In 2014, Jiao Dan carried out the electro-osmotic test of soft clay under different initial and electrified conditions in axisymmetric working conditions on a self-made electro-osmotic consolidation device. It was found that under the same water content and voltage, the electric energy utilization ratio of soil was higher when intermittent electricity was switched on. And the overall difference of soil after electro-osmosis is small[4].

The test method used is based on the ASTM Standard C666 Standard Test Method for Resistance of Concrete to Rapid Freezing and Thawing. Ten mix designs were used for the experimental testing. The test results show that the frost resistance of concrete increases as the water to cement ratio decreases. Actually, for low water to cement ratio or high strength concrete, the frost resistance is excellent even without adding air-entraining agent. For the medium or high water to cement ratio concrete however, incorporating an air-entraining agent is necessary to improve their frost resistance. Incorporation of silica fume improves the frost resistance of concrete, whilst adding fly ash into concrete makes the frost resistance worse. The objective of the research is to determine if a zero air-entrained concrete is durable to freeze thaw cycles.","PeriodicalId":100659,"journal":{"name":"IMPACT of Computing in Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87842839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
